First off, how many miles are on your truck? It may not be your throttle body. Could be plugged cats (my '06 had this issue) or your spark plugs may need changed.
But to answer your question, the throttle body is easy to clean, and I'd still recommend doing it regardless. Get a can of Throttle body cleaner, take off your intake tubing, unplug the two wires attached to it, take off the air cleaner box, and then there are 4 bolts holding it on. You don't even really have to take it off completely, just better cleaning that way. Just don[t spray throttle body cleaner on your MAF, it will ruin it. Get MAF cleaner for that part.

Hesitation between shifts is probably a misfire.. But still clean the MAF with MAF cleaner and the throttle body with throttle body cleaner, it couldn't hurt.
If it does not work then you may have a COP "coil on plug" going out, or a worn spark plug... If you don't have any codes yet, then continue cleaning the induction system to see if it clears up your issue..

The MAF looks like this..
When my 2006 had plugged cats, it was hesitating between shifts as well. It didn't throw any codes, but the plugs were due to be changed, so the dealer changed them as well under warranty. Ford has a 10 yr./100,000 mile warranty on the cats whether you're the original owner or not, so definitely look into that before its too late. A dealer can pop the O2 sensor out and do a pressure test on them to see if thats the culprit.
With 81,000 miles, you probably have the original plugs, and they're probably due to be replaced
